headless exception

Postby KLStringer » Tue Jun 09, 2009 9:22 pm

When trying to install Crossftp I keep getting an "Exception in thread "main" java.awt.headlessexception: No x11 display variable was set, but this program preformed an operation which requires it." error.

I'm trying to set CrossFTP up on a Ubuntu 9.04 server and have zero experience using any form of *nix and have no idea what that error means but I can't get CrossFTp to install or download or whatever its trying to do when I enter in the "javaws http://www.crossftp.com/crossftpserver.jnpl" string from CrossFTP's site.

The first time I tried to install it I got a different error msg saying something about needing java and it gave me a command to run to get it which I did but now I get the error above.

I'm totally clueless as to what I need to do to download or install CrossFTP so any help will be much appreciated.

Thanks

This problem is due to that you are under console only environment, while CrossFTP server is a GUI FTP server rather than a console FTP server. Hence it fails to start up. In the console, you should probably try the console servers, such as ProFTPd, vsFTPd, gFTPd, etd.

OK that makes sense, if I wanted to go with a GUI and not command line interface what would I have to do to go that route? I've never worked in *nix and I've about a week to get everything set up and it needs to be usable by people that have little to no computer skills.

It is actually relatively easy to setup. One week will be good enough. If you need a simple user and permission setup, CrossFTP Server will be fine. For the more advanced configurations, you may go to the proFTPd, glFTPd, vsFTPd, etc.
You can setup the router using the knowledge available in http://www.crossftp.com/kb/entry/32/ Other FTP servers need to be configured similarly. In the next version of CrossFTP Server, we will try to provide the uPnP support so that the router's configuration can be setup automatically.

Our goal is the have a SFTP server for our clients to access to get recordings from, it needs to be low maintenance, easy to administer, and high availability. To get CrossFTP up and working do I need to install some kind of GUI to the server first before trying to install CrossFTP?

I've no experience working with *nix OS's so this is all new territory for me. I don't even know if I'm asking this question on the right forums.

I think you probably should try to use some other console based FTP server. For the security, you can probably try vsFTPd fro the FTPS/TLS, which should be relatively easy to be configured in the console; or the very easy openssh for the SFTP/SSH, which is based on your system's user configuration. For these openssh and vsFTPd configurations and installations, you should try to consult your linux distribution's forum.
